linkedin error after changing site URL

We were testing ASKBOT on an internal site, and changed it (with a redirect) after some testing. We made changes in setting.py to reflect the URL. Google, OpenID, Facebook, Yahoo all still work (we have been unsuccessful in getting Twitter to work yet). LinkedIn worked, but once we made the URL change it no longer works. I even made a new LinkedIn site and changed the keys in Askbot, but it still isn't working. Somewhere it appears it is still referencing the URL, etc. from the old site (ssdt-web-13). What do I need to do in order to get this to work again?
